Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 195 words
A marine fender assembly having a multistage shock-absorbing performance for mounting on a stationary object such as a quay wall, comprising a first shock-receiving member having a substantially flat face in a plane substantially parallel to said wall and facing a side board of a vessel; a pair of first supporting members integrally formed with said first shock-receiving member, said first supporting members extending from said first shock-receiving member toward said quay wall while slightly diverging from each other and forming an inverted U-shape cross-section with said first shock-receiving member; second and third shock-receiving members extending outwardly from said first supporting members at different levels, respectively, each of said levels substantially parallel to said wall; and second and third supporting members integrally formed with said second and third shock-receiving members, said second and third supporting members extending from said second and third shock-receiving members toward said quay wall while slightly diverging from each other, respectively, all of said supporting members being in contact with said quay wall and each of said second and third supporting members being provided at its end with a mounting flange for securing said marine fender assembly to said quay wall.
Claim 2
Dependent Claim 195 words
A marine fender assembly having a multistage shock-absorbing performance for mounting on a stationary object such as a quay wall, comprising a first shock-receiving member having a substantially flat face in a plane substantially parallel to said wall and facing a side board of a vessel; a pair of first supporting members integrally formed with said first shock-receiving member, said first supporting members extending from said first shock-receiving member toward said quay wall while slightly diverging from each other and forming an inverted U-shape cross-section with said first shock-receiving member; second and third shock-receiving members extending outwardly from said first supporting members at different levels, respectively, each of said levels substantially parallel to said wall; and second and third supporting members integrally formed with said second and third shock-receiving members, said second and third supporting members extending from said second and third shock-receiving members toward said quay wall while slightly diverging from each other, respectively, all of said supporting members being in contact with said quay wall and each of said second and third supporting members being provided at its end with a mounting flange for securing said marine fender assembly to said quay wall.
Claim 3
Dependent Claim 83 words
A marine fender assembly as claimed in claim 1 wherein said marine fender assembly satisfies the following conditions; i.e. H 2 = (0.7 to 0.9) × H 1 , and H 3 = (0.5 to 0.7) × H 1 wherein H 1 is a height from said quay wall to said first shock-receiving member, H 2 is a height from said quay wall to said second shock-receiving member and H 3 is a height from said quay wall to said third shock-receiving member.
Claim 4
Dependent Claim 166 words
A marine fender assembly as claimed in claim 2 and further satisfying the following three conditions; i.e. 1. W 1 , W 2 and W 3 = (0.4 to 0.8) × H 1 , 2. t 1 , t 2 and T 3 = (0.1 to 0.4) × H 1 , and T 1 ≦T 2 ≦T 3 , 3. t 1 , t 2 t 3 and t 4 = (0.1 to 0.4) × H 1 , and t 1 = t 2 ≦ t 3 ≦ t 4 wherein H 1 is a height from said quay wall to said first shock-receiving member, W 1 , W 2 and W 3 are widths of said first, second and third shock-receiving members, respectively, T 1 , T 2 and T 3 are thicknesses of said first, second and third shock-receiving members, respectively, and t 1 , t 2 , t 3 and t 4 are thicknesses of said first, second and third supporting members, respectively.
